Repeating comment when refreshed

[Toxicous8]

I have a problem.I made a very usable comment section with a database called comment.But when I refresh the page or open it again it copies the comment that I typed for testing.How do I solve that problem.

Have you checked the code that is being ran on the page-load?

[Toxicous8]

YES!Over and over again.But I don't see anything suspicious.

Well, it's a little hard for us to say what's wrong without any code to look at.

Okay then, here are the codes.

<form action="<?php $_PHP_SELF ?>" method="POST">
Name: <input type="text" name="name" required="required" placeholder="eg. tox!c or benz" /><br/><br/>
E-mail: <input type="text"  name="email" required="required" placeholder="eg. toxic5@gmail.com" /><br/><br/>
Comments : <br/>
<textarea required="required" title="Comments" rows="5" cols="50" name="comment" placeholder="Any comment welcomed...">
</textarea>
<input style="display: inline-block; background:transparent; max-width: 200px;  margin: 50px 10px 30px 10px;  padding: 10px;  color: #000;  border:1px solid #000; cursor:pointer; text-align: center;" type="submit" name="submit" value="Leave comment" onclick="Thank();"/>
</form>

<div style="background:lavenderblush;max-width:60em;position:relative; left:30px;box-shadow:2px 2px 2px #aaa;">
<div style="background:#e9967a;"><br/></div>
<h1>Comments</h1>


<?
include("connect.php");
if(isset($_POST['submit']))
{
$e=$_POST['email'];
$n=$_POST['name'];
$c=$_POST['comment'];
$insert=mysql_query("use codb");
$insert=mysql_query("insert into comment
(name,email,comment)
values ('$n','$e','$c')")or die(mysql_error());
}
$select = mysql_query("select * from comment" );
while ( $row = mysql_fetch_array ( $select )) {
echo '<h3 class="h3">'.$row [ 'name' ].'</h3>';
echo '<i>'.$row [ 'comment' ].'</i><br/>';

echo "<br /><hr/>"; 
}

?>

How come you're inserting into table comment but reading from table comment4?

[Toxicous8]

It was just a mistake I made when pasting it.So I'm guessing the problem is that every time the page loads, the code fetches the data from the database and echo it.Now how do I make the php codes not to duplicate it after reloading???

[Toxicous8]

Hi again, i've updated the codes to the comment section but still repeating. The newer codes are

 <!--   HTML FORM   -->



<h3>Leave a comment</h3>

<form action="<?php $_PHP_SELF ?>" method="POST">
Name: <input type="text" name="name" required="required" placeholder="eg. tox!c or benz" maxlength="25" /><br/><br/>

	







Comments : <br/>
<textarea required="required" title="Comments" rows="10" cols="50" name="comment" placeholder="Any comment welcomed...">
</textarea>

<input style="display: inline-block; background:transparent; max-width: 200px;  margin: 50px 10px 30px 10px;  padding: 10px;  color: #000;  border:1px solid #000; cursor:pointer; text-align: center;" type="submit" name="submit" value="Comment" />
</form>



<div style="background:#fff0f5; max-width:80%; margin-left:7%; box-shadow:2px 2px 2px #aaa; color:#000;">
<div style="background:#e9967a;"><br/></div>
<h1>Comments</h1>






<!--   INSERT COMMENT TO DATABASE   -->

<?php
include('connect.php');   #connect to CODB
        #Assign variables 
$name = $_POST['name'];
$ip = $_SERVER['REMOTE_ADDR'];
$comment = $_POST['comment'];
$submit = $_POST['submit'];


#check if the user has input and store it in COMMENTS else echo out NOT INSERTED
if( isset($submit) ) {
$insert = @mysql_query("USE codb");
$insert = @mysql_query("INSERT INTO comment (ip,name,comment) VALUES ('$ip','$name','$comment') ");
echo '<span style="color:#000;background:rgba(30, 250, 30, 0.1);border:1px solid #0f0;">Inserted</span>';
}else {
    echo '<span style="color:#f00;background:rgba(250, 10, 10, 0.3);border:1px solid #f00;">Please fill out all the fields correctly</span>';
}

?>


<!--   PREVIEW COMMENTS   -->



<?php
include('connect.php');     #connect CODB
        #Assign variables
$s = date("d/m/y h:i:s");    #Assign the date of input
$getquery = mysql_query("SELECT * FROM comment ORDER BY id DESC LIMIT 70")or die(mysql_error());     #get comments



#Check if there are comments and preview them


while ($rows = mysql_fetch_assoc($getquery))  {
    $id = $rows['id'];
    $s = $rows['submission_date'];
    $name = $rows [ 'name' ];
    $comm = $rows ['comment'];


    echo "<br/>$id . <h3 style=\"font-size:25px;\">$name</h3>";
    echo "<i>$s<br/><br/></i>";
    echo "$comm<br/><br /><hr/>";
}


?>

I don't see any reason why the comment would keep inserting unless the user is constantly refreshing the page and resubmitting the data.

[Toxicous8]

Yeah, i've already figured that out. It inserts, fetches and displays the last comment when refreshed. I've read a blog about making comments and at the last part he said that he edited the codes because it was repeating and that he highlighted the line, but i didn't see any highlighted line, maybe because i was using my phone, and when i tried to ask him to write the codes on the comment the page displays blank as if the blog was deleted. Any idea how i can solve this problem??? tnx

[Toxicous8]

And I've also tried the

INSERT IGNORE ...

and

ON DUPLICATE KEY

but no success (the

ON DUPLICATE KEY

doesn't even insert the comments in the first place.
